description	Use rpcclient to enumerate Windows systems via SMB/RPC. Use this skill whenever the user needs to enumerate users, groups, domains, or shares on a Windows target, or when they mention rpcclient, SMB enumeration, RID cycling, SID enumeration, or Windows domain reconnaissance. This skill provides commands and scripts for SAMR, LSARPC, and LSARPC-DS interfaces.

RPCClient Enumeration

A skill for enumerating Windows systems using rpcclient from Samba. This covers user, group, domain, and share enumeration through SMB/RPC interfaces.

When to Use This Skill

Use this skill when:

• You need to enumerate users, groups, or domains on a Windows target
• You have SMB access and want to extract information via RPC
• You're doing Windows domain reconnaissance
• You need to cycle through RIDs to find valid users
• You're working with SAMR, LSARPC, or LSARPC-DS interfaces

Prerequisites

• SMB session established to target
• Credentials (or null session with -N -U "")
• rpcclient from Samba installed

Core Concepts

SIDs and RIDs

• SID (Security Identifier): Unique identifier for a domain
• RID (Relative Identifier): Appended to SID to identify objects within the domain
• Full SID format: S-1-5-21-<domain-rid>-<user-rid>
• Example: S-1-5-21-1074507654-1937615267-42093643874-1111 (user pepe with RID 1111)

Quick Start

# Basic connection (null session)
rpcclient -N -U "" [TARGET_IP]

# With credentials
rpcclient -U [username] [TARGET_IP]

User Enumeration

List All Users

querydispinfo
enumdomusers

Get User Details

queryuser <0xrid>

Get User Groups

queryusergroups <0xrid>

Get User SID

lookupnames <username>

Get User Aliases

queryuseraliases [builtin|domain] <sid>

RID Cycling Script

Use the bundled script to enumerate users by cycling through RIDs:

./scripts/rpcclient-rid-cycler.sh [TARGET_IP] [START_RID] [END_RID]

Default range is 500-1100 (common user RIDs).

Group Enumeration

List All Groups

enumdomgroups

Get Group Details

querygroup <0xrid>

Get Group Members

querygroupmem <0xrid>

Alias Groups

enumalsgroups [builtin|domain]
queryaliasmem [builtin|domain] <0xrid>

Domain Enumeration

List Domains

enumdomains

Get Domain SID

lsaquery

Get Domain Info

querydominfo

Trusted Domains

dsenumdomtrusts

Primary Domain Info

dsroledominfo

Share Enumeration

List All Shares

netshareenumall

Get Share Info

netsharegetinfo <share>

Server Information

srvinfo

Tips

1. RID ranges: Common user RIDs start at 500. Admin accounts often have RIDs 500-515.
2. Null sessions: Try -N -U "" first before using credentials.
3. Error handling: Some commands may fail if permissions are insufficient.
4. Combine with other tools: Use samrdump.py for additional enumeration.
5. Document findings: Save output for later analysis.
